, 2019 Additional file 1: Figure S1. The relationship between RCEXP and maximal mid-expiratory flow rate (MMF). To a certain extent, RCEXP is sociated with MMF with an R2 value of 0.3154 (P < 0.001). There is a gradual increase in RCEXP, especially when MMF is below approximately 1.0 L/s. Figure S2.

Changes in the Flow-Volume Curve According to the Degree of Stenosis in Patients With Unilateral Main Bronchial Stenosis [PDF]
Clinical and Experimental Otorhinolaryngology, 2015 ObjectivesThe shape of the flow-volume (F-V) curve is known to change to showing a prominent plateau as stenosis progresses in patients with tracheal stenosis.

Respiratory Function in Healthy Taiwanese Infants: Tidal Breathing Analysis, Passive Mechanics, and Tidal Forced Expiration. [PDF]
PLoS ONE, 2015 Although infant lung function (ILF) testing is widely practiced in developed Western countries it is not typically performed in Eastern countries, and lung measurements are scarce for Asian infants.

Intrasubject variability of maximal expiratory flow volume curve. [PDF]
Thorax, 1977 Analysis of airflow in the terminal portion of the maximal expiratory flow volume curve has been suggested as a useful test for the early diagnosis of chronic airways obstruction. Whether such an analysis can identify early disease, and whether any subsequent action can prevent the progress of chronic airways obstruction, is unknown and will require ...

Artificial neural network identification of exercise expiratory flow-limitation in adults
Scientific Reports, 2023 Identification of ventilatory constraint is a key objective of clinical exercise testing. Expiratory flow-limitation (EFL) is a well-known type of ventilatory constraint. However, EFL is difficult to measure, and commercial metabolic carts do not readily
